Chinese characters have 4 octets each, likely a typo.  I will double  
check.  Thanks.

Even UTF8-mailbox without alternate address SHOULD allow  
authentication with plain ASCII.  It's up to design.  Although mostly  
the mailbox will be the login name, it doesn't have to be that way.

I think what's more important is to state allowing UTF8 encoded  
characters as part of login name & password.  Multiple different  
credential logins to same mailbox is allowed now, and I guess no one  
intended to restrict it because of EAI environment.

I will revise the doc to have pure ascii credential accessing the EAI  
mailbox.

thanks,
